MASSACHUSETTS, ASSIGNOR TO A. S. CAMP- BELL COMPANY, OF EAST BOSTON, MASSACHUSETTS, A CORPORATION OF MASSA- CHUSETTS CURTAIN-WINDOW INSTALLATION Application filed January This invention aims to provide an improved curtain window installation.

In the drawings, which illustrate a pre ferred embodiment of my invention Figure 1 is an elevation view of the installation, showing part of the cover frame broken away to expose the fastening means;

Figs. 2, 3 and l include enlarged sectional views showing successive steps in assembling the glass-holding frame, the glass and the curtain;

Fig. 5 is an enlarged section on the line 5 5 of Fig. 1, showing an attaching screw in elevation;

Fig. 6 is an enlarged section on the line 66 of Fig. 1; and

Fig. 7 is a plan section on the line 7-7 of Fig. 6.

Referring to the drawings, I have shown a curtain window installation including the curtain fabric 1, a glass 2, and a plurality of metal frame members secured to opposite sides of the curtain to position the glass relative thereto. These frame members comprise a glass-holding frame member 3, a securing frame member 4: and a cover frame member 5. The glass-holding frame member 3 and the securing frame member 4 are secured to opposite sides of the curtain 1 (Fig. 5) by a plurality of attaching screws 6, preferably of the self-tapping variety. These screws pass through apertures in the frame 4 through the curtain 2 and thread themselves into screw-receiving portions 7 presented by the frame member 3.

A cushion strip of self-adhering tape 8 or the like is wrapped about the edge of the glass and extends over the adjacent faces thereof to adhere to the glass 2, the glassholding frame member 3 and the curtain fabric 1, so as to provide a moisture-proof seal at each side of the installation. Thus rain and moisture are excluded from the joints, and the fabric between the frame members is kept dry and free from rot, there by prolonging the life of the installation.

The cover frame member 5 may be secured to the securing frame 4: to conceal the attaching screws 6 and provide a more finished 16, 1925. Serial No. 2,811.

and heater appearing installation, as more fully hereinafter described.

The glass-holding frame member 3 is formed from two pieces of metal (Fig. 2), an inner part 10 and an outer part 12. The inner part 10 is angular in crosssection and presents the screw-receiving portions 7. This part also presents an upwardly curved glasssupporting flange portion 14, which is substantially enclosed by a reversely bent por tion 15 of the outer frame. The two parts secured together in the manner shown in Fig. 2 form a very strong support for the glass because each part supports the other. The two parts are secured together at their outer peripheries in the usual manner.

The securing frame member a is provided at its outer periphery with a beaded portion 16, Figs. 5 and 6, and at the inner edge I have provided, at the long sides of the frame, tongue-receiving pockets 17 as best illustrated in Figs. 6 and 7.

Heretofore the cover frame was secured to the installation by merely snapping the inwardly curved resilient outer periphery 18 over the beaded portion 16 of the securing frame. I have found that relatively long cover frames have a tendency, under certain conditions, to expand and snap off. To remedy this, I have provided at least one tongue 19 at each long side of the cover frame member 5, which engages a tongue-receiving pocket 17 in the securing frame member 4, thereby preventing any spreading action of the cover frame. The cover frame member 5 is provided at its inner periphery with a reversely bent flange portion 20, which extends a substantial distance back upon the frame to add strength thereto. The tongues 19 may be very conveniently formed from this reversely bent flange 20, as best illustrated in Figs. 6 and 7.

In assembling the curtain window to the curtain, the cushion strip 8 is placed about the periphery of the glass 2. The glass is then placed in position in the frame member 3 (Fig. 3) and the curtain fabric 1 is then placed over the frame and glass as best il lustrated in Fig. 4:. Next the securing frame member 4 is placed over the curtain 1 directly above the frame member 3 and the screws 6 are tapped into place (Fig. 5), thereby securin the two frame members 3 and 4: to the curtain 1 and gripping the glass 2 between them. The cloth and excess adhesive tape are then cut from within the aperture in the securing frame by drawing a sharp instrument along the inner periphery of the frame member 4. The cover frame 5 may then be secured to the securing frame member 4 by first springing the frame and working the tongues 19 into the pockets 17 and then snapping the outer periphery of the frame 7 over the beaded portion 16 of the securing frame member 4-, as best illustrated in Fig. 6.

While I have shown and described one illustrative embodiment of my invention, it will be understood that changes involving omission, substitution, alteration and reversal of parts, and even changes in the mode of operation may be made without departing from the scope of my invention, which is best defined in the following claims.
